The physio-morphic influence of 10 different insecticides from 4 major groups of modern synthetic insecticides, compounds with new pesticidal chemistry, surfactants and emulsifiers in form of five different latest recommended schedules were studied on newly released cotton cultivar FH- 672 at Faisalabad (Pakistan). The experiment was laid out in randomized complete block design (RCBD) with four repeats. The physio-morphic characters under present research investigations were plant height, weight of dry leaves, weight of dry branches, weight of dry stem, number of leaves, number of branches, number of unopened bolls, number of opened bolls, leaf area index, leaf area and seed cotton yield. Results revealed that spray-schedules influenced only 4 physio- morphic characters like seed cotton yield, plant height, leaf area index and leaf area. The final performance was negatively correlated with leaf area index and leaf area. All other characters did not show any correlation to seed cotton yield.
